10cm is a Korean indie band that built up their repertoire and experience from performing in Hongdae, a trendy part of Seoul. The group's name comes from the fact that the two members have about 20 cm of a difference in height. They even entered the high school, military and college together, attending Hongik University. They even received the "Rookie Of The Year Award" from Mint Paper, which is a music site that holds such a ranking every year. They even won the 2010 "Best Discovery Award" from Mnet's Asian Music Awards (aka MAMA). One of the things that set 10cm apart from almost 90% of all mainstream acts is that they don't have a manager.

Their musical style can be described as similar to Jason Mraz. It's very light and almost soothing, while maintaining an upbeat factor.
